TAPPET WIRE FOR CORN PLANTER GHEOK ROWER S. No. 298.822. Patented May 20,1884.

To all whom it may concern NITE GEORGE IV. BROWVN, OF GALESBURG, ILLINOIS.

TAPPET IRE FOR CORN- PLANTER CHECK-ROWERS.

SPECIFICATION forming part of Letters Patent No. 298,822, dated May 20, 1884.

Application filed January 22, 1883. (ModeL) Be it known that I, GEORGE WV. BROWN, a citizen of the United States, residing at Galesburg, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in Tappet WVires for Corn- Planter Check-Rowers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in the tappet wire or chain for which Letters Patent No. 258,217 were granted to me May 23, 1882. In said patent the looped end of the section of wire which passes through the knot or .tappet is secured therein, to prevent the knot slipping on the wire in one direction, by coiling the end of the wire upon its main portion. This coiled portion of the wire is objectionable, from the fact that it sometimes engages with the forked lever of the checkrow devices, and operates the seed-slides of the planter too soon.

The object of my present invention is to remedy this defect; and to this end the invention consists in a loop on the end of the section of wire passed through the tappet and secured therein by bending theend of the wire down into a recess or cavity in the tappet, as hereinafter described and claimed.

In the accompanying drawings, which illustrate my invention, and in which the similar letters of reference indicate like parts in all the figures, Figure 1 is a side elevation of the connected ends of two sections of the tappetwire and of a tappet. Fig. 2 is the same elevation of the wire as shown at Fig. 1, and a sectional elevation of a tappet. Fig. 3 is a sec tional elevation of the wire in line w x in Fig. 1, and an end elevation of a tappet.

Referring to the drawings by'letters, A A

I represent the ends of two sections of wire, of g which a tappet-wire or check-row chain is formed. 13 is the tappet, with a cavity, 12, in one side, and a hole, I), through it. The end of one section of wire, A, is bent back upon itself and passed through the hole I), and is formed at its bent portion into an eye, b, which rests in the cavity 1) and holds the tappet from removal at that end of the wire. The end of the section A is bent to form an eye, a, which interlocks with the eye I)", and is held in form by coiling the end a upon the main portion of the section A.

The parts hereinbefore described by letter, except as hereinafter described, are formed and connected as shown in the patent hereinbefore referred to.

To prevent the tappet 13 moving on the section A in the direction shown by the arrow at Fig. 1, I bend its end a outwardly, as shown, and to prevent the bent portion a coming in contact with the forked lever of the check-row devices and being worn thereby, a cavity, c, is formed in the side of the tappet, into which cavity the bent portion a is pressed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A check-row chain combining in its structure sections of wire united by interlocking eyes a b, a tappet or knot through which the bent or loop portion of one section passes, and in which it is held by a short bent portion, a,

- of its end resting in a cavity, a, in the side of the tappet, while the other section is secured by coiling its end upon its main portion, substantially as described, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE WV. BROWN.
